Found the article:
"Earlier this month Portmanís leading man Michael Fassbender left the project after what sources claim was a falling-out with the director."
Just going by the numerous reports here and there of what apparently happened:
- Fassbender backed out after having a fall-out with Ramsey two weeks before production.
- Fassbender's involvement brought an additional $9M to the budger (brought by the foreign investors) so when he left the budget was cut by $9M (from $25M to $16M).
- Ramsey wasn't comfortable changing her vision 2 weeks before the production date because of the budget cut.
- The producer brought in Law who wasn't Ramsey's choice.
...and then all hell broke loose...
